Choose a sleeping bag 選擇睡袋

The sleeping bag that is right for you depends on what you want it for and which features are important. Lightweight and packable for a summer trek and travel or a lot of heat for winter use? Here is a check list of the things you should consider in order to find a sleeping bag that fits your needs.

Temperature

A good rule of thumb is to be prepared for cold temperatures. Choose a sleeping bag that can handle lower temperatures than the lowest temperature you expect. You can always unzip for ventilation if you get too warm. For summer use in the mountains you will need a sleeping bag that can handle around –3°C. For simpler camping and travel in warm countries, a thinner sleeping that can handle temperatures around +10°C is sufficient. In the spring and autumn you will need one that can handle around –10°C and in the winter around –20°C. These recommendations are simply approximations, however, since perceived temperature is personal.

Total weight

How much weight do you want to carry? If you are kayaking or pulling your sleeping bag on a sledge, weight might play less of a role, but if you are trekking many kilometres, a heavier sleeping bag makes your backpack unnecessarily heavy. Down sleeping bags are often lighter than synthetic sleeping bags.

Packed size

Even if a sleeping bag is light, you should keep looking if it is very bulky. Space is often precious, particularly when trekking with a backpack, and you may need the space for something else – food, for example. A down sleeping bag usually can be compressed to half the size of a corresponding synthetic sleeping bag.

Length and volume

Fjällräven sleeping bags come in two lengths: Regular (180 cm) and Long (195 cm). You should choose one that is big enough for you without it being too tight or too roomy. If a sleeping bag is too tight, the padding gets pressed together, which hurts its ability to insulate. If, on the other hand, a sleeping bag is too large, your body volume will not sufficiently heat up the air inside.

Insulation of a sleeping bag

There are two main types of sleeping bags, down and synthetic. Both materials have their strengths and weaknesses

自己適合哪一款睡袋,取決於個人的使用目的和所需的功能而定。選擇適合夏日行山或旅行的輕量及易於收納的睡袋?還是選擇適合冬季活動的保暖睡袋?下面我們提供了一些參考項目,幫助您找到最符合自己需求的睡袋。

溫度

一個大原則就是做好遭遇低溫的萬全準備,睡袋的耐寒溫度應該低於您預期的最低溫,至少太熱還可以打開拉鍊通風。如果是夏季山區之用,可選擇耐寒至零下3度的款式。如果是溫暖地帶的輕便露營或旅行,耐寒10度左右的輕薄睡袋就足以應付。春秋季節需要耐寒 -10 度左右的款式,冬季要到 -20 度左右。上述建議只是一個大概的指標,實際感知溫度還是要以個人為主。

總重量

您預設的行李重量是多少?如果從事泛舟活動,或者可以用雪橇拖運睡袋,重量也許不是太大的問題。但如果是數公里的長途行山,太重的睡袋只會增加背囊的負擔。羽絨睡袋通常比合成填充睡袋較輕。

收納體積

即使睡袋很輕,還要考慮體積是否龐大。空間彌足珍貴,食物等許多物品都需要空間,攜帶背囊行山時更要節省空間。羽絨睡袋通常可以壓縮到合成填充睡袋一半的體積。

長度和容量

Fjällräven的睡袋有兩種長度:一般型(170公分)和加長型(195公分)。您應該依照個人體型選擇夠大的睡袋,不能包太緊,也不能太寬鬆。睡袋如果太小會導致填充物料互相擠壓,損及保暖能力。反之,睡袋如果太大,人體不足以暖化內部空氣。
